OK , but I don´t have instaled any version of Clipper to see the tables and make the changes, and you´re right, when I´d open the tables in Fox, it showed me a warning message that say something like this "If you open this files here, you won´t be able to open them in previous versions of Visual Fox Pro. Do you Accept?" and, ´cause I don´t have Clipper, well, I opened it and made my changes.

Which version of Clipper do you recommend me to install and then delete the records from a selected tables. Then, rebuild the index file and run my application without troubles!!
